void dw2_asm_output_addr_rtx	(	int	size,
		rtx	addr,

   Similar, but use an RTX expression instead of a text label.

void dw2_asm_output_data_sleb128_raw ( )

   Output an signed LEB128 quantity, but only the byte values.

void dw2_asm_output_data_uleb128	(	unsigned HOST_WIDE_INT	value,

			...

   Output an unsigned LEB128 quantity.

void dw2_asm_output_delta	(	int	size,
		const char *	lab1,
		const char *	lab2,
		const char *	comment,
			...
	)

   Output the difference between two symbols in a given size.

   ??? There appear to be assemblers that do not like such
   subtraction, but do support ASM_SET_OP.  It's unfortunately
   impossible to do here, since the ASM_SET_OP for the difference
   symbol must appear after both symbols are defined.

void dw2_asm_output_delta_sleb128	(	const char *	lab1,
		const char *	lab2,
		const char *	comment,
			...
	)

void dw2_asm_output_delta_uleb128	(	const char *	lab1,
		const char *	lab2,
		const char *	comment,
			...
	)

void dw2_asm_output_encoded_addr_rtx	(	int	encoding,
		rtx	addr,
		bool	is_public,
		const char *	comment,
			...
	)

   Like dw2_asm_output_addr_rtx, but encode the pointer as directed.
   If PUBLIC is set and the encoding is DW_EH_PE_indirect, the indirect
   reference is shared across the entire application (or DSO).

     NULL is _always_ represented as a plain zero, as is 1 for Ada's
     "all others".

         Allow the target first crack at emitting this.  Some of the
         special relocations require special directives instead of
         just ".4byte" or whatever.

         Indirection is used to get dynamic relocations out of a
         read-only section.

             It is very tempting to use force_const_mem so that we share data
             with the normal constant pool.  However, we've already emitted
             the constant pool for this function.  Moreover, we'd like to
             share these constants across the entire unit of translation and
             even, if possible, across the entire application (or DSO).

             Other encodings should have been handled by
             ASM_MAYBE_OUTPUT_ENCODED_ADDR_RTX.

References dw2_force_const_mem().

void dw2_asm_output_nstring	(	const char *	str,
		size_t	orig_len,
		const char *	comment,
			...
	)

   Output the first ORIG_LEN characters of STR as a string.
   If ORIG_LEN is equal to -1, ignore this parameter and output
   the entire STR instead.
   If COMMENT is not NULL and comments in the debug information
   have been requested by the user, append the given COMMENT
   to the generated output.

         If an explicit length was given, we can't assume there
         is a null termination in the string buffer.

References asm_out_file, and len.

void dw2_asm_output_offset	(	int	size,
		const char *	label,
		section *	base,
		const char *	comment,
			...
	)

   Output a section-relative reference to a LABEL, which was placed in
   BASE.  In general this can only be done for debugging symbols.
   E.g. on most targets with the GNU linker, this is accomplished with
   a direct reference and the knowledge that the debugging section
   will be placed at VMA 0.  Some targets have special relocations for
   this that we must use.

Referenced by unmark_all_dies(), and unmark_dies().

void dw2_asm_output_pcrel	(	int	size,
		const char *	label,
		const char *	comment,
			...
	)

   Output a self-relative reference to a label, possibly in a
   different section or object file.

void dw2_asm_output_vms_delta	(	int	size,
		const char *	lab1,
		const char *	lab2,
		const char *	comment,
			...
	)

   Output the difference between two symbols in instruction units
   in a given size.

     VMS Delta is only special on ia64-vms, but this function also gets
     called on alpha-vms so it has to do something sane.

   Output an unaligned integer with the given value and size.  Prefer not
   to print a newline, since the caller may want to add a comment.

rtx dw2_force_const_mem ( )

   Put X, a SYMBOL_REF, in memory.  Return a SYMBOL_REF to the allocated
   memory.  Differs from force_const_mem in that a single pool is used for
   the entire unit of translation, and the memory is not guaranteed to be
   "near" the function in any interesting sense.  IS_PUBLIC controls whether
   the symbol can be shared across the entire application (or DSO).

       We use strcmp, rather than just comparing pointers, so that the
       sort order will not depend on the host system.

static int dw2_output_indirect_constant_1	(	splay_tree_node	node,
		void *	data
	)

static

   A helper function for dw2_output_indirect_constants called through
   splay_tree_foreach.  Emit one queued constant to memory.

void dw2_output_indirect_constants ( void )

   Emit the constants queued through dw2_force_const_mem.

const char* eh_data_format_name ( )

   Yield a name for a given pointer encoding.

int size_of_encoded_value ( )

   Given an encoding, return the number of bytes the format occupies.
   This is only defined for fixed-size encodings, and so does not
   include leb128.

int size_of_sleb128 ( )

   Return the size of a signed LEB128 quantity.

int size_of_uleb128 ( )

   Return the size of an unsigned LEB128 quantity.

static int splay_tree_compare_strings ( )

static

   Comparison function for a splay tree in which the keys are strings.
   K1 and K2 have the dynamic type "const char *".  Returns <0, 0, or
   >0 to indicate whether K1 is less than, equal to, or greater than
   K2, respectively.

     The strings are always those from IDENTIFIER_NODEs, and,
     therefore, we should never have two copies of the same
     string.
